Handy Linux Tricks
Submitted by soccerfiend on Thu, 2008-09-25 11:20* What hardware have you got? What version is your BIOS? dmidecode is perfect for this. One that I use regularly is to check the BIOS version without rebooting.
sudo dmidecode -s bios-version
This command returns something like this:
ASUS M2A-VM HDMI ACPI BIOS Revision 0502
* Check device usage
fuser (device)
eg:
fuser /dev/dsp
used for finding out what software has control of a given device. Very usefull when tweaking and troubleshooting a linux pro audio set up.
* rsync backups
rsync -avzue ssh (username)@(hostname or ip):/(path to backup)/* (localpath )
This backs up all files and directories on the remote host and copies to the folder you specify.
* Hard Drive Tuning (Linux)
hdparm (options) (hard drive device) For example:
hdparm -c3 -d1 -S36 /dev/hda
This controls the hard drive, specifically I am enabling dma which speeds up the hard drive, setting i/o to mode 3 which also speeds things up.
